Title: Rotary electric machine and cooling method
Inventor: FUIRITSUPU UIRIAMU ETSUKERUSU
IPC: H02K9/19
Filed: 1980-07-30
Abstract: A vapor trap is provided for use in a liquid coolant supply pipe of a superconductive generator. The supply pipe has interiorly located, a flow constriction, an annular liquid coolant dam, and means for blocking the vapor flow through the central portion of the supply pipe.

Abstract: PURPOSE:To obtain a high thermal insulation characteristics, a refractory characteristics and a high structural strength as well as to form a thin metallic plate by a method wherein copper plates showing a heat-resistant high strength material such as alumina, a glossy state such as stainless steel and showing a low thermal conductivity are piled up repeatedly by (n) times to form air bubbled layers. CONSTITUTION:As a heat-resistant and high strength material 1a, such a material as one having a high refractory characteristic and a chemical stable characteristic such as alumina is used. As a copper plate 1b, material having a heat-resistant feature and a luster as well such as a stainless steel showing a low thermal conductivity. Material showing a stable luster even at a high temperature such as a stainless steel may reflect a heat radiation beam C. As the heat-resistant high strength material 1a and the metallic copper plates 1b are piled up by (n) layers, an amount of transmission of the heat radiation C toward a low temperature wall surface B acting as an outer circumference is reduced to show a value alpha<n>. At the number of layers is increased, the thermal radiation C approaches O as less as possible. Thus, a heat transfer toward the low temperature side wall surface B is remarkably reduced through the heat-resistant high strength material 1a, the copper plate 1b and an air layer 5 existing between these material and said plate.

Title: Dimension measurement device and dimension measurement method using it
Inventor: KISHIDA TAKAAKI
IPC: G01B11/02
Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To accurately measure the dimension of a plurality of parts of an object to be measured by a simple method. SOLUTION: An object to be measured is irradiated with a slit light, and a slit image is obtained on a 2D CCD censor. When an electric signal corresponding to position and light intensity of the slit image is outputted to a calculation device, a dimension measurement process is started. Firstly, a linear approximation is applied to the data of the object to be measured (300). Thereby, data amount is reduced, so a complex regression calculation is not required, for shorter processing time. In addition, a feature amount against the object is calculated (302). Based on the feature amount calculated here, method for measuring dimension of the object is selected (306). In short, an optimum dimension measurement method is selected depending on objects to be measured, so accurate measurement is performed.

Title: Semiconductor light-emitting device
Inventor: MIZUOCHI HITOSHI
IPC: H01L33/30
Filed: 1988-04-26
Abstract: PURPOSE:To keep the temperature dependency of an optical output constant by forming an optical absorption region by fitting a crystal having forbidden band width narrower than an active layer while being adjoined at the rear of the active layer. CONSTITUTION:A partially striped window 10 is shaped into a crystal, and currents are stopped by the thyristor structure of PNPN in a region, in which a current stop layer 4 is interposed, in the same manner as conventional devices. Since, however, an optical absorption layer 12 is formed adjoined at the rear of an active layer 3 in the structure, light generated by the active layer 3 is absorbed completely to the optical absorption layer 12 and cannot reach a rear end face. Consequently, reflected light from a rear end face cannot exist, there is no stimulated emission component in the active layer 3, and light emitted from a front end face is composed only of spontaneous emission light. Accordingly, even when the device is operated at a low temperature, a laser mode is not obtained and an LED mode is acquired, and an optical output is easy to control because it is proportioned to a temperature.
